0:00:26talk about
0:01:09a for a lot
0:01:13what's on
0:01:24so store
0:01:39a everybody's great to be here can you hear me okay in the back
0:01:43so uh
0:01:44it's great to be here to talk a little bit about what uh
0:01:47these signal processing education technical committee
0:01:50is been thinking about as far as a emerging trends
0:01:54in signal processing education as when mention
0:01:57a and the portal caviar i
0:01:59about uh today's talk is
0:02:02but a lot of things were
0:02:03at least today are
0:02:05our opinions
0:02:06and all very important in the break
0:02:09in between the various little some sections of the talk that
0:02:12you jump in with what you feel might be
0:02:15uh other trends more interesting trends or projects going on within these trends that are uh
0:02:21i interesting are also interested in hearing about
0:02:24some trends
0:02:25uh some some trends and some sub
0:02:29so the the the key issues that people are really starting to
0:02:33a a move from actually O uh move from awareness to actual action about over the last years are are
0:02:39for a listed up your the first is
0:02:41the need to move towards a more learn or set or sent
0:02:45uh a learning environment
0:02:47a a meeting uh a loud that the curriculum do adaptable to learners level and also they're their contact
0:02:54and also really try to transfer the responsibility of learning
0:02:57from the instructor to the
0:03:00do right to the lower that cell
0:03:02a a big problem with doing this is there some road blocks
0:03:06right the row blocks related to
0:03:08the fact that the education experience for too many kids today
0:03:11is a a very pass
0:03:13right we sit we listen what we doing right now right we sit we listen we make notes
0:03:18uh we go home and and work on hold
0:03:21a a it it's a very inefficient way to teach a very inefficient way to learn
0:03:25uh one of the problem there's when we try to do things differently we end up with a row block
0:03:31a a a a a a a a
0:03:32educational materials speed a lecture materials text other materials are very flexible
0:03:38and have been very difficult to bring the more learner centric or more ah a a yeah yeah
0:03:45a a teaching a philosophy
0:03:48and finally late when a people are starting to realise that that they need to be thinking about how to
0:03:52bring a lot of the kind of experience that we have to laboratories
0:03:56a hands on experiences into in both the classroom and into that the home
0:04:01a a a of of that the student
0:04:04and then people are also realising that we might build the whole mechanism to do that attack and problem but
0:04:10are we get a
0:04:11put the stuff out there
0:04:12are we gonna maintain a and how are we can ensure that
0:04:15quality remains high
0:04:16right and not D greats oh
0:04:19oh i gonna talk about about four
0:04:22a us that trends that the that people that been uh moving into with over the last couple years
0:04:28and after i finish each one of these little trends
0:04:31when is gonna hop but right
0:04:33in go at
0:04:34people if they have any a
0:04:36oh the first
0:04:38has to do with
0:04:39the idea of moving away from the standard
0:04:41paradigm of text but
0:04:43to more open source or free text books everybody knows what we keep P D a
0:04:47how can we take ideas like this to
0:04:49uh a other kinds of learning you're
0:04:52and uh a key enablers of this or first that technology has come along in about the last two decades
0:04:58that of enabled us to rethink think
0:05:01the text book as instead of as Z six hundred page
0:05:04pile of paper right that's been glued together
0:05:07to think about it instead as a collection of a
0:05:10maybe smaller learning modules jewels are learning object
0:05:14that can be combined together at all kinds of different way
0:05:16oh that instead of having
0:05:18the six hundred page book of which only two hundred and fifty pages is used it any anyone of our
0:05:25is the different two hundred fifty pages
0:05:27by doing things and this like go block a a set up we can rapidly customising reconfigure books so there's
0:05:34just the perfect book for everyone of our differ
0:05:38this would not be possible if that wasn't safe and easy to pull together these like a blocks and the
0:05:43other thing is really move forward the last decade or so are
0:05:46open content licenses things like the creative commons license
0:05:50the make it really easy and also very safe
0:05:52to share
0:05:53a a a very much like the G P L sit
0:05:56really enables the explosion of letting
0:05:59or software
0:06:00quick sure that creative commons some people low
0:06:03if you don't you should write that down creative commons dot org
0:06:07and definitely check it out and and joined at would last i checked
0:06:12there are about two billion
0:06:14creative commons license works up on the inner
0:06:17"'kay" tremendous to men
0:06:19a one example is actually that
0:06:21the project we start or right twelve years ago call connections which is that
0:06:25exactly that's a lego wise text but
0:06:28a shane off the in publishing environment
0:06:31we currently have about a a of hundred of these open text what's
0:06:35you know a whole bunch of different areas from little kids readers for three four year olds
0:06:39there we in india
0:06:40all the way a to a post graduate a course
0:06:44a very yeah uh important thing is that these materials are from folks
0:06:49probe uh world wide
0:06:51yeah both forty different languages
0:06:53and we're supporting right now roughly two to three depending on the but
0:06:56million unique users promote uh coming to the
0:07:00so with
0:07:00actually one and a I T open courseware connections are the two largest and
0:07:04most used uh open education
0:07:07as to give an example of what is like
0:07:09in connections
0:07:10all the materials are viewable as web pages that really the X M L web pages
0:07:15right here but there also view the uh i i on your smart phone or your i can right carry
0:07:21them around or get them through I tunes you for example
0:07:25and everything is also available through a
0:07:27a C print on demand engine that lets you pump out of very professional quality for text books that you
0:07:34can see the price
0:07:35are you hundreds of dollars
0:07:37in some cases cheaper than
0:07:38uh a can be
0:07:40it's and that's real that's
0:07:41basic idea of like connections there's
0:07:43uh a just because it was start by signal processing people there's is a lot of client it already and
0:07:49in signal processing a a a a uh a actually several thousand modules already
0:07:55and that will will come back around of this at the very and what of the purpose
0:07:59this meeting is
0:08:00to get more more than of all the contributing
0:08:02but you
0:08:04when you jump up or
0:08:22a few words with keep year
0:08:24i mean that
0:09:18people here
0:09:19use would keep you your regularly
0:09:23for signal processing like the your work
0:09:26not for you know
0:09:27other other stuff
0:09:29how many if you have actually contributed or and
0:09:33a we keep P and
0:09:37so i think that's one of the things that we need to do as a society i think it's
0:09:41does that
0:09:42membership and the committees need
0:09:45start generating higher quality
0:09:47we keep P entries for a lot of signal pro
0:10:09so it's a soul connections in particular
0:10:12we have a
0:10:13like we keep you we have a very high google karma
0:10:16so anything thing that's in connections and that usually in the top three
0:10:19so yes
0:10:21a that's just because there's someone was christ linking the goes on a but we also do talk to google
0:10:26regularly and i'm actually going to use day
0:10:29a a to talk more with a
0:10:31yeah and in map
0:10:31yeah a quest
0:10:33yeah one of the things is really really nice about
0:10:36open access but you're and the a is you can get
0:10:40absolutely unbelievable amounts of use of your stuff so
0:10:43connection started twelve years ago what i was gonna write a book can instead of writing a book i decided
0:10:49P this
0:10:49right but i did put might but eventually in connections
0:10:53and it's been used the above five million time
0:10:56right which is
0:10:57sure unbelievable the think about when you compare with what i
0:11:01use you would got from
0:11:03okay so that open open education
0:11:06so of video tutorial
0:11:08was about the con academy
0:11:09sure hands
0:11:10"'kay" write it down
0:11:12con academy dot war
0:11:14there's this crazy guy
0:11:15sound so
0:11:17uh i guess i will talk about of for just a minute
0:11:19yeah of a former or ah a hedge fund manager
0:11:23who just started to his cousin
0:11:26actually it is
0:11:27nice nice and F you one day
0:11:30a a remote
0:11:31and he started using software to tutor them
0:11:34and they told their friends and they told their friends and they told their friends
0:11:38he has turned in to basically on once you're of developing a little ten minute video tutorials on
0:11:46basically he wants to do it on everything he used develop O two thousand of the
0:11:51yeah just a little studio that used to be a closet in his
0:11:55house it's now we have a little a that's in
0:11:58a a lot though uh california
0:12:00and he's developed
0:12:01two thousand of these videos a cover basically everything technical indicator a K twelve curriculum
0:12:08like kids education and now we starting to move in the things is very excited move in just circuits in
0:12:13the other areas
0:12:14he an unbelievable teacher
0:12:17you might worry that you know a are you gonna lose your job to sell car right
0:12:22a so the idea of little video tutorials little six minutes seven minute and it tutorials on a on a
0:12:29or on
0:12:30for example do use how to get started with lab of you or how to get started in this lab
0:12:35are are tremendously powerful both as a a a a just support distance learning for dealing with students were not
0:12:42in your campus
0:12:43uh also as time savings the training a lot of people who have
0:12:47and are teaching kids about matlab or a you will use a video tutorials in advance
0:12:52so they don't have to go over the material and class
0:12:55and then also really interesting ideas like reversed instruction anybody or reverse destruction
0:13:01where you basically what all of the lecture materials
0:13:04right you have a regular
0:13:05classroom setting but all the lecture materials are available by
0:13:10students are expected to watch those in advance and the only thing that goes on during the class
0:13:15is actual discussion problems so
0:13:17right of jeffrey herman
0:13:19whose that a postdoc at university of illinois actually talk
0:13:22that you want U C D S P class
0:13:25using this system a laugh summer
0:13:28and it was it tremendously a sec
0:13:31i tremendously
0:13:32and uh the actually one the best paper word that at S P and uh concert
0:13:37a last that
0:13:40any any comments or questions about
0:13:43we jump by no rose home folks
0:13:46i've done a lot with with
0:13:48videos to great effect
0:13:50any comments mark
0:14:29read this paper
0:15:04so how many people here have ever experimented with this kind of
0:15:09as way put it upside down a classroom or reversed
0:15:13but here played around with it
0:15:16i would expect were all pretty traditional
0:15:19"'kay" so there is there are increasing numbers of experiments going on with this and
0:15:24increasing amount of evidence
0:15:26that this is a very very
0:15:29a highly effective way to teach
0:15:32and the thing is very difficult or challenging to all of these you the out there is that it really
0:15:36cuts against the grain of what were used to do it
0:15:39which is
0:15:40going to the board
0:15:41writing for an hour
0:15:42and then having having students uh right at yeah
0:15:45but there was just a very
0:15:47interesting paper it came out of sight
0:15:50a i i think that it should before for last by
0:15:53a group uh U B C vancouver
0:15:56uh uh uh where they actually showed
0:15:58and entire letter a great improvement
0:16:01in the class
0:16:02a a a a a a that the class outcomes learning outcomes
0:16:06uh by doing this
0:16:08basically reversed model
0:16:13a high high
0:16:15get yeah
0:16:17i yes it to change anything great go one
0:16:23a if a
0:16:25so the jury still out
0:16:27the jury is still have
0:16:30the last thing i'll say for moving on is this
0:16:32doing this kind of thing used to actually be really hard
0:16:35is very hard but
0:16:36tools now like yeah
0:16:38can't ages do O which you can and and so other tools
0:16:42which are either very inexpensive or even in some cases
0:16:46to use are uh make it really really quite easy to do this
0:16:51oh enough about a
0:16:52video to as the next is
0:16:54try to bring the lab work to the elements of the laboratory
0:16:58in to the classroom into the home study experience in the homework work
0:17:03uh using a interactive to simulation
0:17:06and the idea here is to move from us C culture right a printed attack
0:17:11more towards that a do culture
0:17:14um i actually interacting with a a a a a different kinds of stimulation
0:17:19and there as as as everyone knows as a number of different environments out there there's a to are acting
0:17:25with we probably missed several
0:17:27um but every from from land you mathematical a a a um man at to
0:17:32a three a J D S P
0:17:34a there are uh
0:17:35also a number of other platforms that people are developing
0:17:39a and you can actually bill
0:17:42extremely elaborate
0:17:44and and very interesting uh uh a simulation is an examples of let people all
0:17:50real world times of problems
0:17:52a a uh in a very very got efficient manner is one a yours right
0:17:57or not we marks right
0:17:59it's it up
0:18:00a basically a a convolution demo and a filter
0:18:04filter design them all that less students get a handle on
0:18:09parameters and all the various different filter structure
0:18:12i i'm sure everybody here
0:18:14male and will add you are met and that one of these two but what it
0:18:18coming is much much easier ways to put these kind of
0:18:22uh simulations up on the web making the i've
0:18:25for your class to use and and folks around the world
0:18:29so any comments about this
0:18:32and the simulation how many people here
0:18:34are using the
0:18:35in their class
0:18:39jim did you have a content
0:18:41are years
0:18:43okay my make a
0:19:02absolutely so there's a
0:19:03yeah building anything like this is always a tradeoff between
0:19:07look and feel and he's a of construction
0:19:11and and
0:19:12all three of these sort of
0:19:14industry standard tools have to different models for how to do this kind of thing
0:19:19different ways to put to distribute them and put them up on the web and so
0:19:24the jury is still out as far as which of these as the best the number of the us
0:19:29a actively experimenting with and then i i hopefully by the community
0:19:34in yeah working more more with all of these will put pressure on these vendors to
0:19:39get even better right then
0:19:41J he's P taken for the
0:20:07oh we you got work so i'll does give you yes or our personal experience
0:20:11is we have work a lot over the years
0:20:14a a putting lad you
0:20:16black these simulations in
0:20:18and uh just do two
0:20:21it it's just become a little bit more tricky lately to put a be since in people still are doing
0:20:26and work also experimenting this summer
0:20:29there now is a clear path
0:20:32to put a at the added to simulations directly in any web page connections pages or any web page
0:20:38and then you get into this
0:20:39trade-off the jim kind of alluded to
0:20:42that uh
0:20:43mathematical looks like at least today it's close we change at least day
0:20:47this is the easiest to get
0:20:49to produce content to put in a web page
0:20:52but it is by far and least flexible as far as look and feel
0:20:56and design
0:20:57all i
0:20:58feel free to talk to the aft
0:21:00like i so you it
0:21:01more about
0:21:02but there is
0:21:02some free
0:21:03how an increasingly easy
0:21:06a a a a ways to do this
0:21:12yeah yeah
0:21:13one one are and there's also some ways a have again it's just a trade of
0:21:17design look and feel
0:21:30jim one work coming
0:21:53right exact
0:22:02yeah yeah yeah you these are fairly
0:23:13so based thinking of these not as just a stand alone
0:23:17a a of feet here
0:23:19but really as a laboratory
0:23:21that's to needs to are it actively engage it's some kind of activity well doing
0:23:26yeah one
0:25:15hmmm L for one yep
0:26:28a remove on
0:26:29okay K people
0:26:30so uh
0:26:32i i another uh
0:26:33error error E R okay so we talk about the led lecturing talk about the text work
0:26:38talk about the lab
0:26:40so now what about the old works right an exam so there's data
0:26:43number projects
0:26:44actively engaged in
0:26:46developing data bases of of questions and answers
0:26:50to to uh for the purposes of a
0:26:52storing but then also share
0:26:54on a much broader uh a base than on in institutional base
0:27:00and and these question as to data bases have a lot of applications
0:27:04self assessment problems for students so they can understand how well they're doing a in the class
0:27:10a automated work systems
0:27:12that take a lot of the pressure off graders and instructors for grading sold work
0:27:17and also provide immediate feedback to the student on
0:27:21whether they did a problem correctly or incorrectly which is been prove and again
0:27:25to to to enhance learning
0:27:27when you have immediate feedback rather than the usual least rice
0:27:31two weeks later you get a homework work back
0:27:33a a great
0:27:34a so all this mentioned to
0:27:36data bases that are being developed the the first and and largest is
0:27:40a a start like to mcclellan that's the signal processing uh a question response system at georgia tech they have
0:27:46actually well over a thousand problem
0:27:48right M
0:27:49i think
0:27:50a a signal processing problems by a number of different faq of the uh a at georgia tech
0:27:55a a we are right they're developing a a a a a a a and of this that we can
0:27:59look quite base
0:28:01it's a a just has a slightly different uh a slightly different architecture but the good thing is that using
0:28:06a web standards like you T I
0:28:09which is the
0:28:10think of it like the each T M L our the X M L for marking ah
0:28:14uh problems in answers
0:28:16a a it's gonna actually be very quite straightforward
0:28:19once all the details are worked out to move the problems back and work
0:28:23tween mean different databases and also directly into your
0:28:27learning management system
0:28:28right if the use a a a black or or or a mood or or and an exact
0:28:33and and a moving forward over the the the next two years we're gonna see just like we just talk
0:28:38one second ago
0:28:40ways and means to track student progress
0:28:43as it work to their home works as they work through not just a semester course the through their tired
0:28:48and both
0:28:49jim's group my group but a number of other folks are actually actively started to work on
0:28:54uh intelligent tutoring systems coding systems for
0:28:58a a a a a a teaching people signal process
0:29:00they can either we use
0:29:02justin said like
0:29:03separated from an actual structure or we in the context of a of the regular class
0:29:09just some couple screen shot is the S P Q R looks like a
0:29:12presents a problem uh let's a student C where they are in the course and how they are doing right
0:29:18like the dashed dashboard
0:29:19i here the top
0:29:21uh so it's very much of course they
0:29:23it's a course organised
0:29:25a a base and the other hand is just intended to be super light weight place
0:29:29for community to develop and share question
0:29:32right and uh under these creative commons
0:29:37a so that this is that to the two databases bright no there some other people work
0:29:41that's some work
0:29:42so T
0:29:43in common
0:29:44wayne in comments audience comments but database
0:29:51oh okay okay okay
0:29:52a a a a
0:29:54does the one question and how many people here we would uh
0:29:58use problems if they were up but that were up a database instead of invading
0:30:02there or
0:30:06i many people here would kick screwed you one of their own problem
0:30:11okay how many people would be here the big one
0:30:14i we people it would be worried
0:30:16if the answers were also i'm their publicly available
0:30:23only a few people work
0:30:37right one good point to point
0:30:42okay i was ahead the last
0:30:44key element is
0:30:45how do we deal with the just to manage all these people in our community developing all all diverse set
0:30:51of educational
0:30:52resources is right diversity means what
0:30:55all kinds of levels of quality so how are we gonna can dock some kind of evaluation of these but
0:31:02as you uh
0:31:03well i think people red
0:31:04as quickly as i
0:31:07a so how don't we uh bring in some of the mechanisms that we we use are very familiar with
0:31:13the ieee
0:31:14in particular peer review
0:31:16are we bring in some of these is are used for for gauging quality but then how do we also
0:31:21a a balance
0:31:22the exclusivity of a peer review
0:31:26with the what we really like to be something more community based or inc
0:31:30so uh what we've done in in a
0:31:34a a a project in collaboration uh S P society and and connections
0:31:39is to develop a sad of we call lenses as
0:31:41which is essentially a
0:31:43a peer review system for material thing connection it could also be applied to simulations
0:31:48could be applied his video tutorials to be applied to this question is a data
0:31:52the basic idea behind a how it works
0:31:54is is a big blue D here is the entire
0:31:57connections repository of eighteen thousand modules and all of these text but
0:32:02there's little kids readers in here there's really good signal processing stuff there may be really bad signal process
0:32:08stuff stuff
0:32:09so what as P society has out
0:32:11is all lan
0:32:13i don't land is is simply a web sort all there's the address you go to ieee see an X
0:32:17dot work
0:32:19you will get to look in the connection is but you will only see the stuffing connections
0:32:23that the ieee
0:32:25right the P society has actually evaluated input their stamp
0:32:29this makes sense to everybody
0:32:32so just to give us a sense of how this
0:32:34how this works
0:32:35let's say you're in google you wanna learn about detection theory
0:32:38you type and detection theory you end up in this connection one to right have you written by don john
0:32:43you don't know done
0:32:44you don't know if it's any good could be crappy right
0:32:47a a a a a but if you notice over here there is a little a land and on that
0:32:51says that this material but endorsed by the S P society we you click on that link
0:32:56in actually take heed of a less them all of the materials
0:32:59that have undergone
0:33:01quality evaluation by yeah
0:33:03and you see don a piece of uh material
0:33:07right so you can think of this as a
0:33:09parallel time to kind to the
0:33:12editorial boards in us it's to develop this idea of a a a land
0:33:17two point in a high quality at a content in the connection we've actually built a open source version a
0:33:24script central if you well that enables us to handle the
0:33:29a all the administration high this call
0:33:33a a there is a a a a P add technical can maybe have a committee
0:33:37that you can think of at be a editorial board for this up particular peer review process
0:33:44i think there's really to or or things that were trying to do here the first is help you user
0:33:49find the high quality stuff
0:33:51and the second as you as a potential author
0:33:54be able to earn endorsed by to fully so that we can move toward the world where educational materials have
0:34:01uh a a a some of the same kind of a cash a as
0:34:06usual close words
0:34:07and zero okay
0:34:09or blurring the lines
0:34:12comments about this
0:34:13know or couple is or what
0:34:18oh can so let me just and by saying
0:34:21a there's is actually a a project started by a number of us
0:34:24called the signal processing education work
0:34:27is actually training with and the staff national science foundation support and ieee
0:34:32collaboration to pull together all of these
0:34:35uh i S and we uh it's X library thing right georgia tech you cat
0:34:39and uh rows home and to to technology and we're really trying experiment but all of these different elements and
0:34:45bring them together into a one
0:34:47a a system
0:34:49where everything is then again a quality review by a the i-th i
0:34:53hi only in i invite everyone to participate
0:34:56a a through the the ieee project the links at the bottom
0:35:00contributing your material
0:35:02also also becoming coming a pure are much like be a review or a paper
0:35:06and also invite you to join
0:35:08uh the then project
0:35:10we intend to
0:35:11grow this nationally internationally over the next
0:35:14do you years
0:35:15there's is a a workshop scheduled schedule twenty the september georgia tech
